[Daily Bearing Net] In order to obtain the best working function from the imported bearings; the cooperation between the inner ring and the shaft and the outer ring and the bearing housing hole is necessary. If the cooperation is not well-joined; the bearing ring can be on the shaft or Circular motion in the bore of the imported bearing housing. This representation is called activity. Once the cooperative outer surface starts to move; the bearing ring will wear excessively at the beginning; it can damage the shaft and the bearing seat; the abrasive fragments can enter the bearing; causing abnormal heating Or oscillate.
Activities are often not able to be avoided by axially clamping the bearings. To avoid movement; it is necessary to supply the necessary interference cooperation for the imported bearing rings that receive the reverse load. Bearing rings that accept the stop load usually do not require interference. Cooperation; unless touch corrosion is caused by oscillation.
In order to select the most suitable cooperation; it is necessary to consider the following:
The characteristic load of the load is the characteristic temperature of the load. The device and the disassembly conditions are related to the inlet bearing device in the thin-walled bearing housing hole or the hollow shaft; it is necessary to supply an interference cooperation larger than normal.
The split housing is not recommended for high precision or tight seat hole cooperation; otherwise the split bearing housing can cause deformation of the outer ring.
Regarding the use of bearings that accept oscillations; interference cooperation should apply to both the inner and outer rings.
